Toshiba 4 head hi-fi stereo vcr model:M-68C,year:Aug 1999,CSA File No:LL38329 (Samsung),pcb board model:M-685 (also VR8800),the vcr plays,fast forwards or rewinds for about 5 seconds.During play the idler wheel does not move only the capstan motor and pulley therefore the vcr eats tape. I cleaned the mode switch and inspected and cleaned the idler wheel assembly but no go,according to a repair tip from:

If the idler wheel does not move, then the takeup reel remains stationary. The uP detects this via the reel sensor and then shuts down the mechanism. In short, there appears to be nothing wrong with your reel sensor. Instead I'd be looking for a slipping belt or slipping clutch or sticky brake pads. Also check that all rotating parts move freely.

To assist in troubleshooting, and to avoid damaging your tapes, you could make a dummy "cheater" cassette and turn the reel(s) by hand.

You should be able to find a point where the driving part is turning but the driven part is not. Test the torque with your fingers. If you suspect a motor, measure the voltage at its terminals.
